Dr. Josette Camilleri

BiographyProfessor Josette Camilleri obtained her Bachelor in Dental Surgery and Master of Philosophy in Dental Surgery from the University of Malta. She completed her doctoral degree, supervised by the late Professor Tom Pitt Ford, at Guy’s Hospital, King’s College London. She has worked at the Department of Civil and Structural Engineering, Faculty for the Built Environment, University of Malta and is currently Associate
Professor at the Department of Restorative Dentistry, Faculty of Dental Surgery, University of Malta. Her research interests include endodontic materials such as root-end filling materials and root canal sealers, with particular interest in mineral trioxide aggregate; Portland cement hydration and other cementitious materials used as biomaterials and also in the construction industry.

Josette has published over 90 papers in peer-reviewed international journals and her work is cited over 3800 times. She is the Editor of Mineral trioxide aggregate. From preparation to application published by Springer in 2014. She is a contributing author to the 7th edition of Harty’s Endodontics in Clinical Practice (Editor: BS Chong) and Glass ionomer cements in Dentistry(Editor: SK Sidhu). She is an international lecturer, a reviewer and a member of the scientific panel of a number of international journals including Scientific Reports (Nature), Journal of Endodontics, Cement and Concrete Composites, Clinical Oral Investigation, Dental Materials, Journal of Dental Research, Journal of Biomedical Materials Research Parts A and B, Journal of Dentistry, Acta Odontologica Scandinavica and Acta Biomaterialia.

A paradigm shift. Is this necessary in root canal obturation?

The purpose of root canal obturation is to prevent infection or re-infection of the root canal space; thus allowing the root treated tooth to remain as a functional unit in the dentition. Microleakage assessment has been the best indication for many years to assess the quality of root canal obturation. A ‘hermetic’ seal was considered to be necessary for a success root canal treatment outcome. There have been several developments with regard to root canal obturation techniques and materials, introduced with the aim of achieving improved quality root fillings and a better clinical outcome. Hydraulic tricalcium silicate-based sealers have been introduced and these materials have different properties to the classical root canal sealers. The presentation will review the material properties and the obturation techniques suggested for hydraulic sealers attempting to address whether a paradigm shift is necessary for root canal obturation.
